Sheet Run
I remember playing this game as a child and I loved it. This activity is best with a large group, but if you can make it work with as few as three people. As a child we used a parachute, but not everyone has one of those lying around the house! A large sheet or blanket works great.
First, have everyone grab hold of the blanket, as evenly spaced as possible. Lift the blanket high over your heads, then pull it down to the floor. As you lift it up, shout out a color. Anyone wearing that color lets go and runs under the sheet while it is still up in the air, and exchanges places with someone else wearing that color. The players wearing other colors try to catch the runners under the blanket or sheet.
If you have only 3 to 5 people, take turns running under while the remaining players lift and drop the blanket or sheet.
